HART message
Diagnostic description
Action
RAM Status – Pass/
Fail RAM corrupt
RAM memory corruption
occurred and was resolved
internally. Repeated triggering
of this alarm suggests a
hardware problem.
Consult VEGA Field
Service.
Sensor EEPROM –
Pass/Fail Sensor EEPROM corrupt
A critical memory corruption
occurred on the sensor pre-
amp board EEPROM that may
not be resolved internally.
To check for
recurrence,
acknowledge the alarm.
Cycle power to the unit.
If the alarm recurs,
there is a hardware
problem. Perform the
procedure to repair the
corrupted EEPROM on
67.
Real Time Clock
Status – Pass/Fail Real time clock fail
The clock failed. This can
cause a miscalculation of
timed events. (If the gauge
had no power for > 28 days,
reset the time and date.)
Reset the time and
date. If they do not
reset, call VEGA Field
Service.
Sensor Temp Probe
–
Pass/Fail Sensor temp probe fail
The sensor temperature probe
may not be functioning, which
results in erroneous
measurements.
Verify the sensor
temperature on the
Gauge Info | Min/Max
History
tab. If the
temperature reads -0.5
°C constantly, the probe
is broken and the sensor
assembly may need
replacement. Call VEGA
Field Service.
Source wipe due –
No/Yes Source wipe due Acknowledge the alarm
by logging a shutter
check in the
Source
Functions tab. See 90.
